 A run chart is a plot of data overtime.  It is a line graph of data points plotted in chronological order.  These data points represent measurements, counts, or

percentages of process output.

 It is a quick and easy approach of deciding

if the process is stable.

 It highlights signals of special causes of

variation in a process such as trends and patterns.

 Used to monitor changes that occur within a process.  A completed chart can show if an implemented improvement

idea was successful.

 The horizontal axis shows the order of the data were collected.  The vertical axis shows the

data values.

 Used to visualize the process

• vertime without regard to

specification limits.

 It often uses the median to show the central location.  Run charts are similar in some regards to the control charts.  It doesn’t show the control limits of the process.  They are therefore simpler to produce.  However, they do not allow for the

full range of analytic techniques supported by control charts.

 Shifts:

• When you see a number of consecutive

points on one side of the center line.

 Trends:

• When you see a number of consecutive

points in the same direction (up or down).

 Patterns:

• When you see a pattern that recurs

a number of times in a row.

A Run Exists When:

 A number of consecutive points lie on one side of the median.  A number of consecutive data points that all increase or

decrease.

 A pattern recurs a number of times in a row.

A Shift A Trend

 Is there a significant trend or pattern that should be investigated?

Tips:

 You need to have 25 points or more in

your data series.

 A long run might be a signal of:

• A special cause variation.
• A beginning of a common cause shift.
• An improvement in the process.

 Whether or not a run is significant depends on the number of

data points plotted.

 Run charts can also be used to track improvements that have

been put into place, checking their success.
